After the tap root exposes itself, can the seed then be placed in a rockwool cube, or does it need to be started in soil. Also, can seeds be germinated from the beginning in a rockwool cube. I am a first time grower, and I am about to start this project. Any help here will be greatly appreciated.
I just wet the rockwool and tear the top up a little bit then stick about 3 seeds in it and let it go. After about 7-10 days i leave the best sprout and cull the rest.
